Right, I have just realised that I have applied the search wizard to the search page rather than the results page!!! DOH
So, I have now tried to apply the wizard to the results page and am now getting a error from the search results page. Prior to running the wizard, I did test the page to make sure that the page populated with content, and all was OK. Now, either from a search or directly typing the address in, I am getting the following error:
Fatal error: Call to undefined function setQueryBuilderSource() in /Users/matthewstuart/Sites/ktc/forum_search_results.php on line 124
I have added the pages again and removed the previous versions I uploaded earlier.
